CAR-COUPLING.

SPECIFICATION forming part ofLetters Patent No. 421,616, dated February 18, 1890.

Application nea June 22,1889. serai No. 315,195. Vein model.)

To @ZZ whom, it may concern:

Be it known that I, THOMAS L'. RIVERS, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented new and useful Twin- Jaw Couplings, of which the following is a specification.

My invention relates to improvements in twin-jaw couplings.

1o The object of the present invention is to produce a car-couplingof simple and inexpensive construction that will automatically couple cars upon their coming together and be capable of limited longitudinal and lateral movement to enable cars to be started successively and facilitate their rounding curves.

The invention consists in the construction and novel combination and arrangement of 2o parts hereinafter fully described, and illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective v view of a car-coupling constructed in accord- 2 5 ance with the invention. Fig. 2 is a reverse plan view. Fig. 3 is a central vertical longitudinal sectional view, and Fig. 4 is a hori zontal sectional view.

Referring to the accompanying drawings,

3o A designates a coupler-head, which is pivoted in a socket or draw-head B, and is provided with rearward projection having inclined sides a, which gradually reduces its width and .makes it capable of limited lateral movement within the socket 01 draw-head B, whereby the coupling is rendered extremely exible and cars are enabled to round curves without liability of cutting the wheels or the rails. v

The coupler-head A is provided at its top 4o and bottom with rearward-extending iianges a', and has perforations a2, through which passes a pin O, that is inserted at the bottom, and is keyed at the top and pivots the coupler-head A to the socket or draw-head B, and

the socket is provided with longitudinal slots or draw-head B4 when the cars are being backed and prevent too far rearward movement of the coupler-head within the socket or draw-head B. The front of the couplerhead has a transverse opening a5, which communicates with a longitudinal recess a, and the hook D is hinged by a pintle d to one side of the coupler-head, and has its rearwardextending arm working in the recess a6, and 6o adapted to be engaged by a sliding bolt E to hold the front portion d2 of the hook across the front of the coupler-head and keep the cars coupled, as will be readily understood.

The bolt E is actuated by a spiral spring F, and has depending from it a rod G, which opcrates in a slot a7, communicating with the recess ai", and is adapted to withdraw the bolt from engagement with the arm d to uncouple the cars. The front of the bolt E is beveled, 7o and when the cars come together the arm d is forced against the bolt, which is depressed sufficiently to allow the arm to pass, but which spring ont and lock the arm against the side of the coupler-head, thereby coupling 7 5 the cars. A V-shaped recess Z9 is provided inthe bottom of the socket or draw-head B to enable the rod G to be operated, and a bar-H is secured across the socket between the recess and the slot Z1 to strengthen the socket 8o at that point,

The socket B is secured between the timbers of a car, and is designed to act as a draw-bar and haveslight longitudinal movement, and is provided in its lower face near its rear end with an opening ZJ to permit access to the interior to key the socket to suitable bars.

From the foregoing description and the accompanying drawings the construction, op- 9o eration, and advantages of the invention will readily be understood.

What l claim is-Y l. A car-coupler comprising the socket or draw-head, provided with longitudinal slots, 9 5 and a coupler-head having a rearward projection provided with inclined sides, whereby the coupler-head is capable of limited longitudinal and. lateral movement within the socket, substantially as described.

2. A car-coupler comprising the socket or draw-head the coupler-head pivoted thereto IOO and provided with a transverse opening and a longitudinal recess, the hook hinged to the coupler-head and having its arm arranged Within the said opening, the sliding bolt having the beveled end, the spring, and the rod depending from the bolt and adapted to withdraw the same from engagement With the coupler-head.

3. A car-coupler comprising the socket or draw-head provided with longitudinal slots b and a Vshaped recess b', the coupler-head provided with the perforated flanges a', and having the transverse opening and longitudinal recess, the hook hinged to the couplerhead and having its arm arranged Within the opening, and the sp ring-actuated bolt adapted to engage said arm and provided with a depending rod, substantially as described.
